摘要: 采用气相色谱,SE30毛细色谱柱,外标法定量,对药物中的甲醇、丙酮、甲苯、二甲苯等溶剂残留进行定性、定量分析。方法的检出限为0.01μg/g,线性范围为0.01-100μg/g,相关系数0.9996,相对标准偏差小于3.88%,方法的回收率在85.8%以上。

Abstract: The residual solvents such as methanol, acetone, toluol, dimethylbenzene in drugs were analyzed qualitatively and quantitatively by gas chromatography with SE30 capillary column and external quantity. The detection limit of this method was 0.01 μg/ g, its linear range was 0.01-100μg/g, its correlation coefficient was 0.999 6, its relative standard deviation was smaller than 3.88 % and its recovery was above 85.8 %.
